Other related processes such as chemical looping gasification (CLG) and reforming (CLR) were aimed to obtain high-quality syngas as a first step for biofuels production. The climate change on the planet because of the emission of greenhouse gases makes decision making urgent. To maintain the limit of 1.5°C of temperature increase as proposed in the Paris agreement, it is urgent to reduce greenhouse gas emissions. In all IPPC projections, carbon capture, use and storage (CCUS) is considered one of the essential technologies to achieve this objective. Within the range of possibilities of CO2 capture processes, chemical looping combustion (CLC) is considered one of the most promising technologies in the production of clean energy due to the low cost related to the process and its flexibility in terms of fuels. In addition, the use of renewable fuels opens the possibility of achieving negative CO2 emissions, one of the key points to get the decarbonization required by 2050.
